Abstract (en)

[origin: WO9904393A2] The invention relates to a stamper for replication of optical discs and to a method of obtaining such a stamper. The method comprises the steps of: a) obtaining a substantially disc-shaped member (100) having a first surface (105; 106); and a second surface (112) forming a back surface of the semi-manufactured stamper; said first surface being provided with a guide track (6; 6') for indicating structurable surface portions (106') of said member (100; 130); said structurable surface portions (106') being flat and substantially unstructured; b) applying a layer (120; 240;) sensitive to irradiation on said first surface (105) such that an unexposed and exposable semi-manufactured stamper is provided; c) enclosing the unexposed semi-manufactured stamper in a protective package such that the sensitive film is maintained substantially unexposed; and d) treating (S30) the semi-manufactured stamper, before performing step c), said treatment including: d1) treating said second surface (112) of the semi-manufactured stamper such that a mean surface deviation value (Rz) below (2) micrometer is obtained.
